US Patent 4 686 905 is refers to a pyrotechnic cartridge for a patent specification European corresponding to frangible projectiles. EP 473 758 is refers to safe pyrotechnic ammunition for training and games or war drills. A cartridge disclosed in this Previous specification includes a sliding case or housing with relation to a plug or plug at the front end of the cartridge. When the cartridge is fired, force is used provided by the propellant gas to push the case or housing back against the bedroom block and to reuse the weapon.
Este conocido cartucho se carga con una pequeña cantidad de agente propulsor además del contenido en un fulminante o detonante. A fin de lograr el objetivo del cartucho, el gas propulsor se alimenta a través de unos canales y pasadizos relativamente estrechados. Las tolerancias de llenado y de mecanizado significan que frecuentemente ocurren variaciones en el peso del agente propulsor adicional y en los regímenes de flujo a través de los canales y pasadizos, y dan lugar a un resultado no fiable.This well-known cartridge is loaded with a small amount of propellant in addition to the content in a fulminant or trigger. In order to achieve the objective of the cartridge, the gas propeller is fed through channels and passageways relatively narrow. The filling and filling tolerances machining means that variations frequently occur in the weight of the additional propellant and in the flow rates at through the canals and passages, and give rise to a result not reliable.
Se supera este problema por el cartucho como queda definido en las reivindicaciones anexas, las cuales ahora serán descritas con referencia a los dibujos que acompañan en los cuales:This problem is overcome by the cartridge as is defined in the appended claims, which now will be described with reference to the accompanying drawings in the which:
La figura 1 es una sección axial a través de un disparo completo de munición, que incorpora el cartucho propuesto, mostrando el disparo completo en posición dentro del cañón de un arma de fuego, antes de disparar;Figure 1 is an axial section through a complete firing of ammunition, which incorporates the proposed cartridge, showing the full shot in position inside the barrel of a firearm, before firing;
La figura 2 es una vista similar a la figura 1, mostrando las piezas o partes del cartucho en las posiciones que ocupan inmediatamente después de la ignición del detonador o fulminante;Figure 2 is a view similar to Figure 1, showing the parts or parts of the cartridge in the positions that occupy immediately after ignition of the detonator or fulminant;
La figura 3 es una vista similar a la figura 1, mostrando las partes del cartucho inmediatamente después de la expulsión, evacuación o eyección del proyectil.Figure 3 is a view similar to Figure 1, showing the parts of the cartridge immediately after the ejection, evacuation or ejection of the projectile.
Con referencia a la figura 1 del dibujo, un disparo completo de munición incluye un cartucho 1 y un proyectil 3 en la forma de una bala con cierre cónico. El disparo completo se representa gráficamente en la cámara de un arma de fuego que tiene un cañón A, bloque de recámara B y percutor C, todo representado esquemáticamente.With reference to figure 1 of the drawing, a complete firing of ammunition includes a cartridge 1 and a projectile 3 in the form of a bullet with conical closure. The full shot is graphically depicted in the chamber of a firearm that has a cannon A, bedroom block B and firing pin C, all represented schematically
El cartucho incluye una carcasa o caja 5, que tiene una forma exterior que se adecua a la cámara o recámara. La caja o carcasa presenta la forma de un componente hueco, a través del cual se extiende un paso o canal de sección transversal circular, el cual tiene una sección 7 posterior de gran diámetro, una sección 9 intermedia estrechada y una sección 11 anterior ahusada, la cual recibe el extremo trasero del proyectil. Una superficie 13 de transición troncocónica se extiende entre las secciones de los canales o pasos 7 y 9.The cartridge includes a housing or box 5, which It has an exterior shape that fits the camera or bedroom. The box or housing has the shape of a hollow component, through of which a passage or channel of cross section extends circular, which has a rear section 7 of large diameter, a narrowed intermediate section 9 and a previous section 11 tapered, which receives the rear end of the projectile. A truncated conical transition surface 13 extends between sections of the channels or steps 7 and 9.
Insertado en la caja o carcasa 5 desde su extremo posterior hay un núcleo 15, que tiene una porción 17 trasera hueca y una porción 19 delantera sólida unidas por una porción 21 intermedia. Las porciones 17 y 18 están configuradas exteriormente a fin de ser un ajuste suave o corredizo en las secciones del paso, canal o conducto 7 y 9 y la porción intermedia 21 es complementaria a la superficie de transición 13. La porción 19 sirve sustancialmente para bloquear la sección de paso o conducto 9 contra la fuga de gas a través de la misma.Inserted in the box or housing 5 from its end rear there is a core 15, which has a hollow rear portion 17 and a solid front portion 19 joined by a portion 21 intermediate. Portions 17 and 18 are configured externally in order to be a smooth or sliding adjustment in the sections of the step, channel or conduit 7 and 9 and intermediate portion 21 is complementary to transition surface 13. Portion 19 serves substantially to block the passage section or conduit 9 against gas leakage through it.
Dentro de la porción del cuerpo posterior 17 del núcleo hay una cámara 23, la cual se ensancha en su extremo posterior para recibir un fulminante o detonante explosivo 25. Pasando a través de la porción del cuerpo intermedio 21 hay una pluralidad de taladros 27 radiales hacia afuera en sentido oblicuo, convenientemente tres o cuatro en número. Los extremos exteriores de los taladros 27 miran hacia la superficie de transición 13.Within the rear body portion 17 of the core there is a chamber 23, which widens at its end later to receive an explosive fulminant or trigger 25. Passing through the intermediate body portion 21 there is a plurality of radial holes 27 obliquely, conveniently three or four in number. Outer ends of the holes 27 face the transition surface 13.
La cámara 23 sirve de primera cámara de expansión y será aplicada aquí como tal.Chamber 23 serves as the first expansion chamber and will be applied here as such.
Cuando se dispara el arma de fuego, el percutor C choca contra el fulminante o detonante 25, que detona y descarga el gas propulsor en la primera cámara de expansión 23. El gas pasa a través de los canales o conductos 27 al espacio definido entre la porción intermedia 21 y la superficie de transición 13 del taladro. La superficie exterior de la porción intermedia 21 sirve de pistón, de manera que el gas hace avanzar al núcleo 15 hacia la parte posterior para crear una segunda cámara de expansión 29, como queda representado en la figura 2. Durante esta acción, la porción de núcleo delantera 19 se extrae a través de la sección de paso o canal 7. El movimiento hacia atrás del núcleo 15 cesa cuando un anillo de retención y de estanqueidad 13 en la parte posterior de la sección del paso o canal 7 se encaja en una superficie de tope 33 en el extremo delantero de la porción del cuerpo trasero 17, como se representa en la figura 3. El contacto entre el anillo obturador o de estanqueidad y la superficie de la porción del cuerpo trasero 17 impide la fuga de gas a la parte posterior durante la operación o funcionamiento del cartucho descrito mas arriba. Durante esta secuencia de operaciones, después de la extracción completa de la parte delantera del núcleo 19 de la sección de paso delantera 11, el gas en la segunda cámara de expansión 29 se descarga instantáneamente a las secciones de paso o canal 9 y 11 para expeler o expulsar el proyectil.When the firearm is fired, the firing pin C it hits the fulminating or detonating 25, which detonates and unloads the propellant gas in the first expansion chamber 23. The gas passes to through the channels or conduits 27 to the defined space between the intermediate portion 21 and the transition surface 13 of the bore. The outer surface of the intermediate portion 21 serves as a piston, so that the gas advances the core 15 towards the part later to create a second expansion chamber 29, as is represented in figure 2. During this action, the portion of front core 19 is extracted through the passage section or channel 7. The backward movement of core 15 ceases when a retaining and sealing ring 13 on the back of the section of the passage or channel 7 fits into a stop surface 33 at the front end of the rear body portion 17, as is represented in figure 3. The contact between the sealing ring or sealing and the surface of the rear body portion 17 prevents gas leakage to the rear during operation or operation of the cartridge described above. During this sequence of operations, after complete removal of the front of the core 19 of the front passage section 11, the gas in the second expansion chamber 29 is discharged instantly to the passage sections or channel 9 and 11 to expel or eject the projectile.
El movimiento hacia atrás del núcleo aplica fuerza al bloque de recamara para reutilizar el arma.The backward movement of the core applies force the bedroom block to reuse the weapon.
Como la operación o funcionamiento del cartucho propuesto no depende del uso del agente propulsor adicional, al que fue proporcionado por el fulminante o cebador 25 y la expulsión del proyectil se efectúa en respuesta a la apertura de la sección del paso o canal 9 y la descarga de gas sustancialmente instantánea en este paso o conducto, el cartucho propuesto no sufre la tendencia hacia un funcionamiento no fiable que caracteriza al cartucho conocido de la EP 473 758.As the operation or operation of the cartridge proposed does not depend on the use of the additional propellant, to which was provided by the fulminant or primer 25 and the expulsion of projectile is made in response to the opening of the section of the passage or channel 9 and substantially instantaneous gas discharge in this passage or conduit, the proposed cartridge does not suffer the tendency towards unreliable operation that characterizes the cartridge known from EP 473 758.
Como el cartucho propuesto no tiene los pasos o canales finos del cartucho conocido, al menos el núcleo es especialmente adecuado para su moldeo partiendo de material plástico.As the proposed cartridge does not have the steps or fine channels of the known cartridge, at least the core is especially suitable for molding starting from material plastic.
El cartucho también se podría volver a usar sustituyendo el fulminante o, alternativamente, sustituyendo el conjunto del núcleo y fulminante. El cartucho propuesto también es menos tóxico que el cartucho conocido porque no se requiere ningún agente propulsor adicional.The cartridge could also be reused replacing the fulminant or, alternatively, replacing the core set and fulminant. The proposed cartridge is also less toxic than the known cartridge because no additional propellant.
El cartucho se podría usar como un cartucho de fogueo si se prescinde del proyectil.The cartridge could be used as a cartridge fuse if the projectile is dispensed with.
Aunque la superficie de transición se representa como troncocónica y la superficie exterior de la porción intermedia 21 complementaria a la misma, cabe la posibilidad de que, al menos, la superficie exterior de la porción intermedia 21 se extienda radialmente, siempre que unos taladros u orificios 27 se dispongan apropiadamente para alimentar gas a la segunda cámara de expansión.Although the transition surface is represented as conical trunk and the outer surface of the intermediate portion 21 complementary to it, it is possible that at least the outer surface of the intermediate portion 21 extends radially, provided that holes or holes 27 are arranged properly to feed gas to the second chamber of expansion.
